ACETYLEN E-GAS-G EN ERATOR LAlVI P.

SPECIFICATION forming part of Letters Patent No. 610,210, dated September 6, 1898. Application filed May 6, 1898. Serial No. 679,891. (No model.)

To @ZZ whom t may concern,.-

Be it known that I, HENRY W. IVELLS, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Acetylene-Gas Bicycle-Lamps, of which the following` is a specification.

My invention has relation to an acetylenegas lamp, and in such connection it relates particularly to the construction and arrangement of the generator of the gas adapted to be burned in the lamp and to means for automatically controlling by the generated gas the iiow of the Iiuid to the calcio carbid adapted to generate the resultant gas and to prevent undue generation of the gas.

The principal object of my invention is to provide a simple, reliable, or effective gasgenerating appliance for burning the gas resultin g therefrom in the lampof a bicycle or other similar appliance and an appliance in i which the gas generated controls the supply of fluid to matter adapted to develop thegas, and, further, in which the appliance is provided with means whereby the supply of fluid is regulated so as to prevent undue generation of gas, and an acetylene-gas lamp for bicycles or similar purposes being provided which can be used with safety.

My invention, stated in general terms, con- -sists of an acetylene-gas lamp when constructed and arranged substantially as hereinafter described and claimed.

In the accompanying drawing is illustrated, in side elevation and in section, a lamp embodying the particular features of my invention.

Referring to the drawing, A represents a headlight or suitable bicycle-lamp.

a is a generator-chamber adapted to contain a charge b, of calcio carbid' or similar matter, removably secured to the base a of the headlight or lamp A. Within said chainber a is provided a vertically-perforated tube c, in which is mounted a sponge or other ab` sorbent material c', for a purpose to be presently more fully explained. Y

d is a funnel-shaped circular delector-plate carbid in the chamber d for the absorbed water by the material c/ is brought into the presence of the carbid, resulting in a burning-gas beinggenerated from the same. The pipe j Iis provided with a manual key f and with a ball cheek-valve g, as shown. Above the ball check-valve is provided an extension f2, into which is secured a branch pipe z', preferably encircling the wall of the reservoir e and extending therefrom into the upper part of the generator-chambera., and through which the gas is adapted to freely circulate. The generation of gas from the calcio carbid in the generator-chamber d is afforded by the supp ply of uid from the reservoir through the pipe f when the ball check-valve g is raised from its seat g' onto the absorbent material o.

and then through the perforations of the tube cinto the carbid. If the generation of the gas becomes excessive, the pressure of gas generated and'` passing through the branch pipe e' will cause the ball check-valve g to be forced against its seat g/, and thereby to prevent further flow of the fluid to the carbid until the excessive generation of gas has been relieved through the consumption or blow-olf of the same through the burner d5 when the key a of the lamp is in its' open position, as illustrated.

The operation of a lamp provided with an acetylene-gas generator of my invention, as hereinbefore described, is as follows: The manual key f in the supply-pipeffrom the reservoir e is turned to an open position, as illustrated, and the iiuidwill thereby flow through the said pipe f, raising the ballof the check-valve g from its seat g', and pass then downward onto the absorbent material c', and by capillary attraction of the calcio carbid or similar matter in the chamber a,

for the absorbed water in the tube c is the Water absorbed by the carbid to generate a gas which rises therefrom and passes to the burner a5 in the headlight of the lamp and burned from the same when the key a@ is in its open position, as illustrated. Should the supply of fluid to the carbid become excessive or greater than is required, this undue generation can be relieved by the gas generated in the chamber a rising. through the branch pipe t' and pressing down upon the ball of the check-valve g to cause the same to be firmly seated, thereby preventing further supply of fluid to the carbid until the quantity of generated gas is reduced to the point to permit the volume or weight of the water from the reservoir flowing through the pipe f to raise the ball of the valve g, when further generation will again proceed and furnish a requisite supply of gas for being consumed by the burner a5 of the lamp A.

f Having thus described the nature and object of my invention, what I claim as new, and desire to secure by Letters Patent, is

l. An acetylene-gas generator, comprising a lamp provided with a burner, two chambers, one for fluid secured in rear of said lamp and the other for carbid located below said lamp and detachably connected therewith, a pipe connection from said fluid-chamber with said carbid-chamber, a ball checkvalve seated in said pipe connection and elevated by the flow of fluid from said fluidchamber, and a branch gas-pipe from the upper part of' said ball check-valve, encircling said iluidchamber and connected with said carbid-chamber and adapted to depress or seat the ball of said valve in said pipe connection to cut od the supply offluid to the carbid in its chamber by the pressure of the generated gas therefrom against vsaid ball, substantially as shown and for the purposes specified.

2. An acetylene-gas generator, comprising a lamp provided with a burner, two chambers, one for fluid secured in rear of said lamp and the other for carbid located below said lamp and detachably connected therewith, a perforated tube in said carbid-chamber adapted to contain an absorbent material, a defiector-plate interposed between the lamp-base and carbid-chamber and extending into the same and the throat of said plate fitting into said perforated tube,'a pipe connection from said fluid-chamber with said carbid-chamber, means in said pipe connection actuated by the fluid of said fluid-chamber to permit of the flow of the fluid to the carbid in its chamber and a branch gas-pipe. from said pipe connection about said means 4and connected with said carbid-chamber to cut o the supply of fluid to the carbid in its chamber by the pressure of the generated gas therefrom, substantially as shown and for the purposes specified.

In testimony whereof I have hereunto set my signature in the presence of two subscribing witnesses.

HENRY XV. WELLS.
